Friend doesn't believe in dinosaurs.

So my christian friend just told me out of the blue that he doesnt believe in dinosaurs and thinks the bones were made with plaster and are faked. Then he asks me "Have I shocked you?" Something is telling me that he just said that to get a reaction out of me as if he were trying to get me angry or something. But I'm not sure. What do you think I should write back to him?

Sadly, that reminds me too much of the creature Dr. Frankenstein created, who had to live out his life alone, never having been asked to be created, reminding me of Jeff Goldblum's line from Jurassic Park, "You did it because you could, but you never asked if you should."
